1.sys模块实现的进度条
import sys import time def view_bar(num): for i in range(num): time.sleep (0.5) ret = " %s%d%%"%((i+1)*"=",i+1) sys.stdout.write(ret) sys.stdout.flush() if __name__ == '__main__': view_bar(10)
2.OS模块
import os # print (os.getcwd()) D:Pythonday6 # print (os.curdir) . # print (os.pardir) .. # os.makedirs("dir1/dir2/dir3") 在getcwd()的目录下新建dir1/dir2/dir3 # os.removedirs("dir1/dir2/dir3") 在getcwd()的目录下删除了dir1/dir2/dir3 # print (os.stat("s1.py")) os.stat_result(st_mode=33206, st_ino=15199648742533178, st_dev=1121161508, st_nlink=1, st_uid=0, st_gid=0, st_size=335, st_atime=1469633380, st_mtime=1469633380, st_ctime=1469547918) # print (os.path.join("d:pythonday6","lib","commons.py")) d:pythonday6libcommons.py # print (os.path.join("d:pythonday6","lib")) d:pythonday6lib
